This is brilliant, everything at our office is Google hosted, and all our accounts are associated with Google. I personally use Apple products with the exception of my workstation which is W8.1 - but I am constantly remote accessing it from home, in the field, holiday. And I have constantly been paying for fixed IP or having to check the current IP for the two WAN ports to gain access, I also need user names and passwords for my user accounts and another account. Plus I have to enable RDP on every windows machine, and open a new custom port and program the router to pass them all through (since each PC has to have a different port of the single WAN IP is to connect directly to the right PC).
Now I can use the Google account on each PC which already has Chrome and the app launcher installed and simply choose that account from my iPad or other remote computer. So easy and reliable, by passing all that other crap.
I know there are thirdparty programs that do this but you either have to pay for each license, or put up with adds.
And as for spying, who cares nothing to hide here.
